Estream Portable Water Turbine Power

Estream portable water turbine

Estream is a portable water-power generator that converts any type of moving water, such as that from a river or stream, into stored energy to charge most of today’s usb-connected mobile devices, even while you are off the grid. The project currently has a Kickstarter campaign where folks can pledge money and get the Estream early when it goes into production.

It takes about 4.5 hours to fully charge 6,400mAh built-in battery by running water. Once fully charges, the battery can charge up to 3 smartphones, GoPros or even tablet PCs, twice as fast as a regular outlet. It is rechargeable, so as long as you you have access to running water, you can continue to charge your devices – even on the longest adventures.

Why we chose water?

We are all aware of the importance of renewable energy for a sustainable future. Fortunately, as portable solar and biomass power generators are becoming more popular, we are increasingly closer to closing the personal power gap on the planet. More reliable than solar and more efficient than wind, water is one of the world’s most powerful renewable energy resources, and it’s all around us.

  • 24-hour stability: As long as you have access to water, even if the current slows, the Estream will provide a stable connection to energy. Can you imagine power as reliable and powerful as what we use at home provided by water beyond the grid?
  • Energy efficient: water is the most efficient natural energy resource on earth. So even our compact design can produce energy 3 to 20 times faster, with more energy output, than similar products in the market. And no extra fuel resource such as heavy jug of gasoline required to generate. All you need is Estream and current water.
